CONCRETE CLIP.

Application filed March 15, 1926. Serial No. 94,671.

In building construction it is common practice to mold around beams, channels, columns, girders, angle irons, or the like,

' concrete or fire-proofing material.

Practical experience has shown that in many cases the surrounding concrete or fire-,

proofing material will break away from the shapes surrounded thereby, particularly at (or adjacent the edges or corners thereof, due to insuflicient bonding between the two.

One of the means heretofore employed for reinforcing the bond between the surrounding concrete, fire-proofing material, or the like, and beams, channels, girders, etc., has consisted of clips of one kind or another attached to the latter and embedded in the former.

.One object of the present invention is to provide a reinforcing device or clip of novel construction including means whereby a clip of requisite strength may be produced from a rod or Wire of minimum cross-sectional area.

It is also an object of" the invention to provide a clip or reinforcing device in which one part thereof is interlocked with another part in such manner that the latter is adapted to be supported in a most efiicient way by the former.

Another object of the invention is to provide a clip of novel construction having means whereby the surrounding concrete, fire-proofing material, or the like, at the corners or edges of a girder, beam column, angle iron, or the like, is more securely held and bound than heretofore, as far as I am aware, has been practical.

Another object of the invention is to provide a clip of novel construction including means whereby the portion of the clip which extends crosswise of the channel, girder, column, or the like, upon which it is mounted is engaged and supported by portions of the clip having direct connection with such channel, girder, etc.

Clips embodying the invention may be employed separately and independently of shape which may be. preferred.

accompanying drawing in which I have illustrated one form of a convenientembodiment of the invention. 7

In the drawing:

Fig. 1 is a viewv in transverse section of an I-beam provided with a clip embodying the invention;

Fig. 2 is aview in side elevation of the said beam from which is suspended a plurality of clips embodying the invention, which clips are connected at intervals to a spacing rod or bar; and

Fig. 3 is a view in perspective of the clip separated from the said beam and from the said spacin rod or bar.

Clips em odying the invention are particularly useful and efiicient in connection With ceiling structures in which concrete, fire-proofing material, or the like, is supported upon horizontal beams which may be of I-shape, channel-shape, or of any other In such cases the reinforcing clips are secured to the lower'edge portions of the said beams and reinforce and strengthen the bonding rela tion between such lower edge portions and the surrounding concrete, fire-proofing material, or the like to such extent as to practically eliminate the possibility of the separation of such surrounding material from the supporting beams.

In the construction as illustrated I have shown the device embodying my invention as being employed in connection with an I- beam 1. As already indicated, however, it may be employed in connection with beams, columns, girders and the like of any other suitable or desired crosssectionalshape or configuration.

It will be noted that the device consists of a rod orwire having an intermediate barlike portion 2 which extends in general parallel relation to the beam or girder with which the device is connected. The opposite ends of the intermediate portion 2 terminate in loops 3 formed by bending the wire upwardly, inwardly, and then transversely of the opposite end portions of the intermediate part 2. The end of one of the said loops extends upon one side of the portion 2, while the end of the opposite loop portion ext-ends upon the opposite side of the part 2. The extended end portions of the rod or wire are bent around the oppoportions of the rod or Wire extend across the adjoining loops, the said extensions ,being located upon opposite sides of the device. These extensions constitute in effect chords of the loops 3 providing segments a upon the outer sides thereof. Theopposite end portions of the rod or wire extend a considerable distance beyond the loops 8, as indicated at 5 in Fig. 8.

For the purpose of securing the said clips or reinforcing devices upon a beam, girder, or the like the extended end portions 5 are placed upon opposite sides thereof and are then bent into engagement with some portion of such beams, girders, or the like. In

the construction as illustrated the said ex tended end portions 5 are placed upon the outer edges of v the oppositely extending flanges of the lower side of the beam 1 with the upper edges of the loops 3 in contact with the lower sides of the outer edge portions of the said flanges. The said opposite ends 5 are then bent down upon the top sides of the said flanges, as is clearly shown in Fig. 1 of the drawing, so that the clip or reinforcing device is firmly and securely attached to and adapted to be held upon the I-beam 1. i

It will be apparent upon inspection of Fig. 1 of the drawing that the intermediate portion 2, which in a ceiling structure is the bottom portion of the device, is suspended by the portions 6 intermediate the bends 7 and the interlocking points 4, previously referred to. It will also be apparent from said figure that when the clip or reinforcing device is in position upon a beam, girder, or the like the segmental portions (in of the loops 3 extend beyond the edges or corners of the beam, girder, or the like, to which it may be secured, so that an increased reinforcingeffect of the bond between the surrounding concrete, fire-proofing material, 01' the like and the beam, girder, or the like is obtained.

The dash and dot lines 8 indicate the concrete, fire-proofing material, or the like which surrounds the beam.

In practice these clips are placed at intervals along the beam, girder, or the like with which they are associated, and preferably they are held in fixed spaced relation to each other by means of a spacing rod or bar 10 to which they may be secured in any suitable manner.

It will be seen that by my invention I have prorided a device in which deformation of the loops at the opposite ends of the intermediate part or portion 2 is practically impossible; and also that rods or wires of minimum cross-sectional area afford the requisite strength to effect efficient bonding between the beam, girder, or the like and the surrounding concrete, fire-proofing material, or the like.

Having thus described my invention, what I claimand desire to secure by Letters Patent is:

1. A concrete clip consisting of a metal rod or wire of suitable length having an in termediate portion terminating in loops at its opposite ends and the said rod or wire having its end portions extended across the said loops and transversely of the said intermediate portion, which end portions are adapted to engage a girder, beam, column, or the like.

2. A. concrete clip consisting of a rod or wire having an intermediate part, the opposite ends of which terminate in loops, the opposite end portions of the said rod or wire being extended transversely of the opposite end portions of the said intermediate part upon opposite sides thereof and then across the said loops in directions practically at right angles to the said part, and forming segments upon the outer sides of the said extended portions.

3. A concrete clip comprising an intermediate art which terminates in loops at its opposite ends and the said clip having extended end portions which interlock with the opposite end portions of the said intermediate part inwardly of the outer sides of the said loops, which extended end portions are adapted to be interlocked with a beam, girder, column or the like.

4. A concrete clip consisting of a rod or wire having an intermediate part which terminates at its outer ends in loops, the inner ends of said loops being extended upon opposite sides of the said intermediate part and the end portions of the said rod or wire ex- I tending across the said loops in directions substantially at right angles to the length of the said intermediate part, which ends are adapted to engage a beam, girder, column, or the like for attaching the said clip thereto. 5. A concrete clip consisting of a rod or wire having an intermediate part which terminates at its opposite ends in loops, the opposite end portions of the said wire being extended laterally, inwardly, and thenoutwardly and then bent around the outer end portions of the said intermediate part and then extwded crosswise of the said loops in directions transversely of the said intermediate part to provide segments of the said loops beyond the said cross-wise extended end portions and the said end portions being adapted to be placed in outside relation to portions of a beam, girder, column, or the like and to be bent into engagement therewith to e'il'ect interlockingof the said clip with such beam, girder, column or the like, the segmental portions of the said loops eX- tending beyond the adjacent portions of the said beam, girder, column or the like to which the said clip may be attached.

6. A concrete clip consisting of a rod or wire of suitable length, the opposite end portions of which are bent laterally in transverse relation to the length of the said rod or wire, inwardly in general parallel relation to the length of the said rod or wire, then laterally and outwardly toward the intermediate portion of the said wire to form loops, the said loops being connected by an intermediate part and the said opposite end portions extending underneath the opposite end portions of the said intermediate part and then transversely thereof across the said 15 loops to divide the latter into segments, substantially as described;

In testimony that I claim theforegoing as my invention, I have hereunto signed my name this eleventh day of March, A. D. 1926.
